Steel grating rusts. Aluminum corrodes. Wood rots. But molded FRP grating just keeps working – even in the harshest chemical plants and offshore platforms. Let’s walk all over the science.
HISTORY / ORIGIN
Traditional grating materials – steel, aluminum, and wood – had major flaws: rust, conductivity, heavy weight, and short lifespan in wet or corrosive environments. The need for a better solution grew in the 1960s, especially in chemical processing, marine, and wastewater industries. Enter Fiber Reinforced Polymer (FRP) technology. By the 1970s, manufacturers began molding fiberglass and resin into grating panels. Today, molded FRP grating is the go‑to choice for platforms, walkways, trench covers, stair treads, and mezzanines – anywhere safety and durability matter more than weight.
TYPES OF MOLDED FRP GRATING
Standard Meshes (Square or Rectangular) – Most common. Available in 1" x 1", 1.5" x 1.5", 2" x 2" patterns. Provides excellent slip resistance.
